简要总结
This study is a pilot trial of a smartphone app to promote sustainable and healthy eating, running for 10 weeks. The app aims to promote general wellbeing in the working population. The investigators are interested in the feasibility and acceptability of the plant-based recipes and information pages, so the focus will be on how people engage with these features and how they meet their needs.
Participants will be randomised into three groups:
- General information (no app).
- Standard app (app as it stands).
- Enhanced app with recipes and behaviour change recommendations (app + messages).
Data on demographics and food choice will be collected at the start and end of the intervention. A subset of participants will also take part in short interviews to talk about their experiences.
详细描述
Overall aim:
This pilot trial aims to understand the feasibility and acceptability of a health and wellbeing app. The main focus is around the plant-based recipes and information pages delivered through the chat functionality.
Specific objectives:
The primary objective is to understand the feasibility and acceptability of setting up and running a trial with the app, focusing on the reach, adoption, implementation, and maintenance. The secondary objectives are to explore the indicative efficacy of the app in facilitating more sustainable and healthier diets, measured by a change in meat and legume intake, to what extent the recipes and information pages contribute to this effect, and whether there is a relationship between the self-perceived capabilities, opportunities and motivations to consume a sustainable and healthier diet.
